Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a medical guide wire dipping device. Background Technology

[0002] With the development of medical technology, medical guidewires are widely used in various interventional procedures, and most interventional procedures use multiple guidewires. Since the guidewire needs to enter the human body, it needs to be dipped and coated, that is, a lubricating coating is applied to the surface of the guidewire to reduce friction during the process of entering the human body, thereby reducing harm to the patient.

[0003] Existing guidewire dipping devices typically use a straight up-and-down method to dip and coat guidewires. When dipping and coating multiple guidewires, this method may cause the lubricating coating to accumulate or be unevenly distributed at bends or special shapes of the guidewires, increasing friction between the guidewires and the human body and thus aggravating harm to the patient. Summary of the Invention

[0004] This utility model discloses a medical guidewire dipping device, which aims to solve the technical problem that when existing guidewire dipping devices use a straight up-down method to dip multiple guidewires, the lubricating coating accumulates or is unevenly distributed at the bending or special shape of the guidewire, which increases the friction between the guidewire and the human body and thus aggravates the harm to the patient.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A medical guidewire dipping device includes a dipping solution tank. Two triangular supports are bolted to both sides of the tank. An arc-shaped dipping module is located on one side of each triangular support. The arc-shaped dipping module includes a rotating shaft. Movable holes are formed on opposite sides of the two triangular supports, and the rotating shaft is movably connected to the two movable holes. A servo motor is fixedly connected to one side of one of the triangular supports. The drive end of the servo motor is connected to one end of the rotating shaft via a coupling. A limit plate is fixedly connected to the outer wall of the rotating shaft. Multiple connecting frames are fixedly connected at equal distances to both sides of the limit plate. A common mounting frame is fixedly connected to one side of two connecting frames on the same side. A common annular support plate is bolted to both sides of the multiple mounting frames. A common limit seat is fixedly connected to one side of two annular support plates. An automatic replenishment module, including a liquid storage tank, is located on one side of the dipping solution tank.

[0007] By incorporating an arc-shaped immersion coating module and an automatic replenishment module, the immersion coating solution can be automatically replenished when it is low, reducing manual operation steps. At the same time, it allows the medical guidewire to enter the immersion coating solution in an arc-shaped trajectory, better conforming to the bending shape of the guidewire. This ensures that the contact time and angle between various parts of the guidewire surface and the immersion coating solution are more uniform, resulting in a more even distribution of the lubricating coating on the guidewire surface. This reduces friction during the guidewire's entry into the human body, thereby minimizing harm to the patient.

[0008] In a preferred embodiment, connecting seats are fixedly connected to both sides of multiple mounting frames, and the same air chamber is fixedly connected to the opposite sides of two connecting seats on the same mounting frame. An opening is provided at the bottom of the air chamber, and a connecting tube is fixedly connected inside the opening. One end of the connecting tube is fixedly connected to a suction bladder. A compression spring is fixedly connected to the bottom of multiple air chambers, and a piston is fixedly connected to one end of the compression spring. Both the compression spring and the piston are movably connected inside the air chamber. Telescopic rods are fixedly connected to the side of multiple connecting seats away from the suction bladder, and the same fixing seat is fixedly connected to one end of two telescopic rods on the same plane. The fixing seat fits into the interior of a limiting seat, and limiting holes are provided at equal intervals on both sides of the fixing seat and the limiting seat. Control valves are movably connected to both sides of multiple connecting tubes, and a delivery tube and a touch-up coating tube are movably connected to the ends of two control valves on the same connecting tube, respectively. The delivery tube is located above the fixing seat. Touch-up coating grooves are provided on both sides of multiple fixing seats and limiting seats, and one end of the touch-up coating tube is located inside the touch-up coating groove.

[0009] The device, equipped with a rotating shaft, a limiting plate, a mounting frame, and an annular support plate, operates by activating a servo motor. The servo motor causes the rotating shaft to move in a circular motion, simultaneously moving the limiting plate and mounting frame, and simultaneously moving the annular support plate. This allows the medical guidewire to enter the immersion solution tank in an arc-shaped trajectory, better conforming to the guidewire's curvature. This ensures more uniform contact time and angle between different parts of the guidewire surface and the immersion solution, resulting in a more even distribution of the lubricating coating on the guidewire surface. This reduces friction during the guidewire's entry into the body, thereby minimizing harm to the patient.

[0010] In a preferred embodiment, a horizontal plate is bolted to one side of the immersion coating tank, and the top of the horizontal plate is fixedly connected to one side of the liquid storage tank. The liquid storage tank has an outlet hole on the side facing the triangular support. A water pump is connected to the outlet hole through a pipe. A water supply pipe is fixedly connected to one side of the water pump. A pipe groove is opened on one side of the immersion coating tank, and the water supply pipe is fixedly connected to the inside of the pipe groove. A water supply nozzle is fixedly connected to one end of the water supply pipe and is located inside the immersion coating tank.

[0011] Equipped with a reservoir, a water supply pipe, and a supply nozzle, the device operates by activating a water pump. The pump uses the water supply pipe to allow the stored liquid in the reservoir to enter the coating solution tank through the supply nozzle. This avoids manual replenishment and reduces the risk of incomplete coating of the guidewire due to insufficient coating solution in the tank. Consequently, it reduces manual operation steps and minimizes harm to the patient caused by uneven coating of the guidewire.

[0012] As can be seen from the above, the medical guide wire dipping device provided by this utility model uses arc-shaped dipping to replace the original straight-up-down dipping method, so that the medical guide wire enters the dipping liquid in an arc-shaped trajectory, which better conforms to the bending shape of the guide wire, makes the contact time and angle between various parts of the guide wire surface and the dipping liquid more uniform, and makes the lubricating coating on the guide wire surface evenly distributed, reducing the friction of the guide wire during the process of entering the human body, thereby reducing the harm to the patient.

[0021] Reference Figure 1 , Figure 2 and Figure 3In a preferred embodiment, connecting seats 308 are fixedly connected to both sides of multiple mounting frames 305, and the same air chamber 314 is fixedly connected to the opposite sides of two connecting seats 308 on the same mounting frame 305. The bottom of the air chamber 314 has an opening, and a connecting tube 312 is fixedly connected inside the opening. One end of the connecting tube 312 is fixedly connected to a suction bladder 311. Compression springs 315 are fixedly connected to the bottom of multiple air chambers 314, and a piston 316 is fixedly connected to one end of the compression springs 315. Both the compression springs 315 and the piston 316 are movably connected inside the air chambers 314. The side of the multiple connecting seats 308 away from the suction bladder 311 is fixedly connected to... The system is equipped with telescopic rods 309, and two telescopic rods 309 located on the same plane are fixedly connected to the same fixed seat 310 at one end.

Control valves 313 are movably connected to both sides of multiple connecting pipes 312, and two control valves 313 located on the same connecting pipe 312 are movably connected to the ends of a delivery pipe 318 and a touch-up coating pipe 317, respectively.

[0022] Reference Figure 1 and Figure 4 In a preferred embodiment, a horizontal plate 401 is bolted to one side of the immersion tank 1, and the top of the horizontal plate 401 is fixedly connected to one side of the liquid storage tank 402.

[0023] Working principle: When the device is in use, the servo motor 301 is started. The servo motor 301 causes the rotating shaft 302 to drive the limiting plate 303 and the mounting frame 305 to move in a circular motion, while the annular support plate 306 moves together. At this time, the medical guide wire enters the immersion liquid tank 1 in an arc trajectory. While the mounting frame 305 moves, the control valve 313 on one side is opened. The piston 316 uses its own gravity to compress the compression spring 315, so that the gas inside the suction bag 311 is delivered to the outside through the delivery pipe 318. When the mounting frame 305 moves, the limit plate 303 and the mounting frame 306 move together. When the device moves to its lowest position, piston 316 and compression spring 315 reset, causing suction bladder 311 to draw coating solution from inside the coating solution tank 1. At this time, another control valve 313 is opened, allowing the coating solution to replenish the guide wire portion limited inside the limiting seat 307 and the fixed seat 310. When the device is in use, in order to avoid the guide wire being incompletely coated due to the reduction of coating solution inside the coating solution tank 1, water pump 403 is started. Water pump 403 uses water supply pipe 404 to allow the stored liquid inside the liquid storage tank 402 to enter the coating solution tank 1 through the supply nozzle 405.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions.
